The grieving parents of children killed in the Connecticut school massacre
call for action top prevent similar tragedies, warning "this can happen
in any community".

Originally from Rhode Island, Ms Hockley had lived in the UK with her husband for nearly 18 years before deciding to move back to Connecticut in search of a better life for her son.

"It's been one month since I lost my son, Dylan and 25 other families lost their loved ones. At times it feels like only yesterday and other times it feels as if many years have past," she said.

The Sandy Hook group says it wants to hold open-minded discussions about a range of issues, including guns, mental health and safety in schools and other public places.

"The Sandy Hook promises the start of our change. It's a promise we make for our community, but we need a nation of communities to join us in making and delivering on these promises if we are going to achieve true transformation. I don't know yet what these changes are. I come with no preconceived agenda," Ms Hockley said.

In the meantime, grieving parents of the Sandy Hook shooting victims have a message to the country.

"Like everyone here we want to bring about changes that will stop a tragedy such as this from happening to any community ever again. Because this can happen in any community. Your community," said Jeremy Richman, father of Avielle Rose Richman, a Newtown shooting victim.
